This monograph is based on 20 years of research with patients who have experienced pathology in one hemisphere of the brain. It deals with brain mechanisms in human communicative behavior, and with related motor functions, from a broadly biological point of view. In so doing, the work discusses the possible evolutionary origins of human communication, the relation of brain mechanisms in communicative behavior to analogous nonhuman behaviors, and the neural systems involved in various levels and kinds of communication. In addition, noncommunicative mechanisms which parallel those used in communication--such as manual and oral praxis, and constructional behavior-- are outlined in detail. Individual differences in brain organization for such functions, related to hand preference and sex, are also explored. Although there is extensive reference to central nervous system pathology, the emphasis throughout is on how the findings contribute to understanding normal brain mechanisms. Much new data is presented along with the theoretical treatment of human communication which emphasizes a behavioral rather than a linguistic approach. This in turn provides continuity with nonhuman primates and early hominids. The work will interest psycholinguists, cognitive psychologists, neurologists, clinical neuropsychologists, speech pathologists, and advanced students in these fields.

Utilizing a historical and international approach, this valuable two-volume resource makes even the more complex linguistic issues understandable for the non-specialized reader. Containing over 500 alphabetically arranged entries and an expansive glossary by a team of international scholars, the Encyclopedia of Linguistics explores the varied perspectives, figures, and methodologies that make up the field.

This book is an entry into the fierce current debate among psycholinguists, neuroscientists, and evolutionary theorists about the nature and origins of human language. A prominent neuroscientist here takes up the Darwinian case, using data seldom considered by psycholinguists and neurolinguists to argue that human language--though more sophisticated than all other forms of animal communication--is not a qualitatively different ability from all forms of animal communication, does not require a quantum evolutionary leap to explain it, and is not unified in a single "language instinct." Using clinical evidence from speech-impaired patients, functional neuroimaging, and evolutionary biology to make his case, Philip Lieberman contends that human language is not a single separate module but a functional neurological system made up of many separate abilities. Language remains as it began, Lieberman argues: a device for coping with the world. But in a blow to human narcissism, he makes the case that this most remarkable human ability is a by-product of our remote reptilian ancestors' abilities to dodge hazards, seize opportunities, and live to see another day.

Written by respected academics in neuropsychology, this sixth edition guides students on a comprehensive journey of discovery through the realm of contemporary human neuropsychology. The book has a clinical focus throughout.

As the papers in this special issue demonstrate, gonadal hormones have powerful effects on the development of the brain and behavior in human beings, as in other species. Both androgens and estrogens affect behavior throughout development, from early prenatal life through adulthood, as demonstrated in studies with a variety of methods in several species. The articles also describe attempts to identify the mechanisms--neural and basic behavioral--that mediate hormonal effects on complex human behaviors. This issue testifies to the breadth and vitality of research into the ways that hormones affect the development of sex-typical behavior, and illustrates several important themes that have emerged in human psychoneuroendocrinology. First, it is now clear that hormones do affect human behavior, and the important questions relate to the mechanisms and details of hormone action. Second, there are many ways to study hormone effects on human behavior, and this issue describes these methods and their products. Third, traditional conceptions of hormone-behavior relations have generally stood the test of time, but recent developments have begun to reveal the complexity of these relations. Taken as a whole, the articles in this special issue are interesting and worthwhile reading in their own right, but they may also act to stimulate developmental neuropsychologists to consider hormones in their own studies.
